DETAILED DESCRIPTION

Hereinafter, specific characteristics and advantages of the presentembodiments will be described in detail with reference to theaccompanying drawings. The same reference numerals provided in thedrawings indicate the same members. Moreover, detailed descriptionsrelated to well-known functions or configurations will be ruled out inorder not to unnecessarily obscure subject matters of the presentembodiments.

A button-type pencil cosmetic dispenser 100, as illustrated in FIGS. 1and 2 in a large scale, includes a container body 110, a piston 200, afirst rotation member 300, a second rotation member 400, a thirdrotation member 500, and a rotation conversion means 600.

Firstly, a container body 110 will be described. The container body, asillustrated in FIGS. 2 and 3, stores contents at an interior thereof,and has a discharging hole 111, where contents is discharged, at anupper portion thereof.

Next, a piston 200 will be described. The piston 200, as illustrated inFIGS. 2 and 3, discharges contents through the discharging hole 111 asascending/descending inside of the container body 110.

Next, the first rotation member 300, coupled to a lower surface of thepiston, as illustrated in FIG. 2, is coupled to a lower surface of thepiston 200, and has a first screw thread 301 provided at an outercircumferential surface thereof, a flat surface 302 cut flat verticallyprovided at an upper end thereof, and a protrusion 310 provided at alower end thereof.

Next, a second rotation member 400 will be described. The secondrotation member 400, as illustrated in FIGS. 2 and 3, is provided withan engaging screw protrusion part 410 which is screw-coupled, fittedwith the first screw thread 301 of the first rotation member 300, andcontrols an upward movement of the first rotation member 300 whenmeeting the protrusion 310, further comprising a second screw thread 401at an outer circumferential surface thereof.

The protrusion 310 in the above controls the upward movement by theengaging screw protrusion part 410 formed at an upper end of the secondrotation member 400 and thereby prevents the first rotation member 300from being separated from the second rotation member 400.

Furthermore, the protrusion 310 induces the second rotation member 400to ascend after the first rotation member 300 reaches a top dead point.

Meanwhile, it is preferred that a separation preventing member 420 isprovided at a lower end of the second rotation member 400 for preventingthe second rotation member 400 from being separated from a thirdrotation member 500.

Meanwhile, it is preferred that the piston 200 is made to have only avertical movement inside the container body 110, but not to have arotational movement. At this time, the rotational force delivered to thepiston 200 through the first rotation member 300 and the second rotationmember 400 is far smaller than the operational force delivered for thepiston 200 to ascend/descend by the first rotation member 300.Therefore, an ascending distance while the first rotation member 300 orthe second rotation member 400 is making one rotation becomes a pitch ofthe first screw thread 301 or the second screw thread 401. Since atorque applied during one rotation, assuming there is no work loss, isconverted into a force applied while ascending as much as the ascendingdistance, a rotational force by the torque is much smaller than theoperational force delivered for ascending/descending. Accordingly,whereas the rotational force is much smaller than a frictional forcereceived when the piston 200 contacts an inner wall of the containerbody 110, the operational force received for ascending/descending islarger than the frictional force received when the piston 200 contactsan inner wall of the container body 110, such that the piston 200 can bemaintained not to be rotated on the container body 110, simultaneouslymaking an ascending movement.

This principle can be summarized as the followings: ‘the rotationalforce<the frictional force received when the piston 200 contacts aninner wall of the container body 110 <the operational force deliveredfor ascending/descending’. Accordingly, it is preferred that a shape anda material should be determined for the piston 200 so as to satisfy suchconditions.

Meanwhile, in another exemplary embodiment, just by making thecross-sectional shape of the piston 200 to a shape, which corresponds tothe cross-sectional shape of an inner was of the container body 110,into a shape, such as an oval or a polygon, it is possible that thepiston 200 can make only a vertical movement inside the container body110, but not a rotational movement.

Next, a third rotation member 500 will be described. The third rotationmember 500, as illustrated in FIGS. 2 and 3, is screw-coupled, fittedwith the second rotation member 400, further comprising a third screwthread 501 coupled to a second screw thread 401.

Next, a rotation conversion means 600 will be described. The rotationconversion means 600, as illustrated in FIGS. 2 and 3, is coupled to thethird rotation member 500 and rotates the third rotation member 500 toone side direction according to vertical movement of a button 660.

As exemplary embodiments embodying the rotation conversion means 600, avariety of exemplary embodiments can be possible. As one of theexemplary embodiments, as illustrated in FIGS. 2, 5 and 6, the rotationconversion means 600 is preferred to further comprise a rotationconversion part cap 610, an elastic member 620, a rotation operatingmember 630, a vertical motion member 640, and a vertical guide 650.

In this case, the rotation conversion part cap 610, as illustrated inFIGS. 2 and 6, has a through hole 611 formed at an upper portion thereoffor the second rotation member 400 to pass through, and is configured tohave the third rotation member 500 disposed at an inner portion thereof.Meanwhile, for the vertical guide 650 and the rotation conversion partcap 610 to be engaged, an engagement protrusion 612, as illustrated inFIGS. 2, is preferably provided at a lower portion of the rotationconversion part cap 610, and an engagement groove 652 is provided at anupper portion of the vertical guide 650 for the engagement protrusion612 to be inserted and coupled.

The rotation operating member 630, as illustrated in FIGS. 2 and 5, isprovided for being supported in a downward direction by the elasticmember 620 installed at the rotation conversion part cap 610, with acoupling protrusion 631 engaged at a coupling groove 510 which is formedat the third rotation member 500, and with an inclined surface 632 and aflat part 633 provided in order and in repetition, as illustrated inFIGS. 2, 5 and 6.

The vertical motion member 640, as illustrated in FIGS. 2 and 6, isprovided at a lower portion of the rotation operating member 630, abilateral inclined surface 641 is provided repeatedly at an upper endthereof, and a rotation preventing protrusion 642 is provided extendingin a downward direction of the bilateral inclined surface 641 along anouter circumferential surface.

Adding to a configuration illustrated in FIGS. 2 and 6, the verticalguide 650, as illustrated in a dotted line in FIG. 5 for indicatingalong with elements inside, is engaged to a lower portion of therotation conversion part cap 610, receives the elastic member 620, therotation operating member 630, and the vertical motion member 640 at aninterior thereof at a state of being engaged with the rotationconversion part cap 610, is provided with a unilateral inclinedprotrusion part 653 repeatedly at an upper end along an lower innercircumferential surface thereof, and is provided with a vertical guidegroove 651 wherein each of the rotation preventing protrusion 642 isinserted and guided at each of an unilateral inclined protrusion part653.

The operation of the rotation conversion means 600 having aconfiguration in the above, referring FIG. 6, is described as thefollowings.

Firstly, in an early state as illustrated in FIG. 6(a), while therotation operating member 630 is elastically being supported to adownward direction by the elastic member 620, most portion of theinclined surface 632 is touched with the unilateral inclined protrusionpart 653 in a state of the rotation operating member 630 descending, andthe rotation preventing protrusion 642 connected with the button 660 isdisposed inside the vertical guide groove 651 in a state of the rotationpreventing protrusion 642 descending.

When the button is pressurized in the state above, the vertical motionmember 640 starts to ascend accordingly as illustrated in FIG. 6(a). Inthis case, a vertical side surface 632a connected to the inclinedsurface 632 and a vertical surface 632b connected to the unilateralinclined protrusion part meet each other and prevent a rotational motionto one side direction, such that the rotation operating member 630 getsto ascend along with the vertical motion member 640 while an upper apexof the bilateral inclined surface 641 of the rotation preventingprotrusion 642 is pushing up the inclined surface 632.

After that, when the button 660 is pressurized to the end as illustratedin FIG. 6c , the bilateral inclined surface 641 and the unilateralinclined protrusion part 653 are connected each other. At this time, therotation operating member 630 elastically supported to a downwarddirection by the elastic member 620 descends along the bilateralinclined surface 641 and the unilateral inclined protrusion part 653which are connected with the inclined surface 632, being rotated by anelastic force of the elastic member 620.

Lastly, even after the button 660 descends and goes back to the originalposition, as illustrated in FIG. 6d , the rotation operating member 630,by an elastic force of the elastic member 620, keeps on rotating anddescending along the bilateral inclined surface 641 and the unilateralinclined protrusion part 653, and then goes back to an initial state,completing one operational cycle.

Meanwhile, an ascent/descent and its rotational operation according tothe rotation operating member 630 as in the above delivers only therotational operation to the third rotation member 500 through a couplingprotrusion 631 connected to a coupling groove 510 further provided atthe third rotation member 500. Through this, thus, the pressurizing thebutton 660, in general, is converted to a rotational operation of thethird rotation member 500. Accordingly, it is possible to dischargecontents easily with one hand by employing a button type for thecontents discharge.

Furthermore, for improving user convenience, a button-type pencilcosmetic dispenser, as illustrated in FIG. 2, is preferred to furtherinclude a discharging member 120 coupled to the discharging hole 111 andvertically provided with a movement passage 121, and an applicationmember 130 coupled to the movement passage 121.

Meanwhile, for user convenience, as illustrated in FIGS. 1 and 2, it ispossible that a button-type pencil cosmetic dispenser further includesan outer container 700 which imbeds the container body 110 therein and alower portion thereof open for the button 660 to be exposed; a finishingmember 710 coupled to an upper portion of the outer container 700 andcovering and fixing a lower portion of the application member 130; and acover cap 720 detachably coupled to an upper portion of the outercontainer 700. In this case, it is possible that the outer container 700and the cover cap 720 can have the cross-section thereof embodied into avariety of designs such as a circle, a triangle, and a square.

As described in the above, a button-type pencil cosmetic dispenser 100,as illustrated in FIGS. 3 and 4, can be manufactured in a compactstructure wherein a piston can be raised by adopting a configurationwherein a first rotation member 300 and a second rotation member 400 canbe raised in order, such that it is possible to store more contentsinside a container body.
